`Application 'filed March 31, 19145. Serial No. 18,235'l To all whgm itmay concern Be it known thatA we,`HAnRY D. LATHROP and WALTER H.PAULsoN, citizens of the United States, and residents of the city kofChicago, county .of Cook, and State of Illinois, have jointly-inventedcertain new and useful Improvements in Milk-Can-Washing lIachines, ofwhich the following is a speciiication. d ll l Our invention'relates toimprovements in can washing machines especially designed for' use inthe"washing and sterilizing of milk cans and more 'specically. toimprovements in the canv reversing mechanism used in connection withthis class of machines.

The object of our invention is the production of a can reversingmechanism I of this character which will be of durable and eco- Ynomicalconstruction, and one which will be highly eiiicient in operation.

Other objects will appear hereinafter. With these objects in view, theinvention consists `in `the, combinations and arrangements-of partshereinafter described and claimed.

The invention will be best understood by reference tothe` accompanyingdrawings forming a part of this speciication, and in'which, n

Figure 1 is a side elevation of the discharge, end on a can washingmachine equipped with reversing mechanism embodying the invention, Fig.2 is a vertical longitudinal section of a portion of theconstructionshown in Fig. 1, illustrating the A manner of reversing of a-can, andFig. 3 is an enlarged detailsection taken on line' y-Jy of'Fig. 2.

The preferred form of construction, as illustrated in the drawings,comprises a can reversing mechanism which is especially designed for usein connection with a machine adapted for the washing of milk cans andthe covers therefor. Said machine comprises guides 42, as shown in Fig.2, upon which the milk-cans A are adapted to be slid in invertedposition, the latter, in the movement of the'same along said guidesbeingv thoroughly .washed and sterilized.

The washing and sterilizing mechanism is not shown in the presentapplication, inasmuch -as the same forms no part of the subject matterof this application which is directed only to mechanism through themedium of whch'the milk cans, after being washed and'sterilized areinverted to upright position for discharge from the machine. `This canreversing mechanism which is arranged at the discharge ends of theguides 42 comprises a substantially semicircular frame v43 which is.pivoted or trunnioned at 44 to tlie upper ends of postsv 45, preferablyof a vertical adjustable Construction. The pivots oritrunnionsl44 arelocated intermediate the endsy of the'frame 43 and adjacentl th'elongitudinal 4v"edges,

thereof but in sucha position that said frame is adapted normally'of itsown ,weight` to assume a position shown in Fig. "'1, thatfis onein whichthe same willV be adapted to receive a can discharged from the guides 2,the can, 1n being discharged from said guides, being adapted to dropinto said frameuas clearly showfn in Fig. 1. Said frame is formedtoconformwith the shape of the can, the semi-'circular body thereofengaging with the body of the can andthe lower end thereof being formedfor engage- V ment with the neck of the can. Upon-the .depositof the canonto said framer43, the weight of the can will cause'said frame toVswing upon its pivots or trunnions 44 to the position sho-wn in Fig.- 2thereby accom. plishing the reversing of the can or rocking of thev sameto upright position. The

frame 43 will deposit the can onto inclined'.

discharge guides 46 between which is arranged a reinforcing medialchannel 47.

In order tobreak the fall of thecan, in i the deposit thereof onto theguides 46o.so

-as to insure against toppling of the can, as

might otherwise result from too sudden jar, a cushioning device in theform of a plate 48, is providedA which is pivoted at 49. A weight 50cooperates with said plate to normally hold thesame in an elevated pom'j tion, as shown in Fig. '1,- a chain 51 serving to limit the downwardmovement of the weight. With this arrangement, in thereversing of thecan, and deposit thereof onto the guides 46, the outer .or yforward edgeof the lower end of the can will contact withA the plate 48, the latter,under the weight of `the can, yielding downwardly.

with the result' of very gently settling the can to position `on theguides 46. A roller 52 is providedv on the frame 43 f'oren'gagement withthe rearward edge of the lower end of the canin order to preventrelative longitudinal sliding ofthe can in thedisposition. l M guides 46are inclined, as shown, at such an angle that the ycans depositedthere-` ed as at 46( in order to scope of the appended claims,

Having described-ourinvention what we charge thereof from said frame,saidroller to initial position for thereception'of the succeeding can,the location of the trunnions or pivots44, as shown and above mentioned,and the balancing of theframe between supports 4 5, insuring positivelythe automatic swinging of said frame to' its first The on will slidedownwardlyby gravity and be discharged from the guides. The guides -46are pivotally mounty permit of adjustment of the angularity thereof tosecure the desired rapidity of movement of the cans thereon.'

l While we have illustrated and described the preferred form fconstruction for carrying our invention'into effect', this is capa bleof variation and I departing from the spirit of the invention. We,therefore, do not wish to be limitedto the precise details ofconstruction .set forth, but desire to avail ourselves of suchvariations and modilications as come within theA claim as new and Patentis :l

2. Ina device of the class described, the combination of a guide.; andanoscillatory member substantially semi-cylindrical in -form,.t he axisof oscillation of which is located intermediate its ends and adjacentthelongitudinal edges of said member, said I member being arranged forcoperation Upon. the .release lower ends of'said'v Vmain ,l can guide;
